Theiiiii'ain trunk and branch flues may he inserted flushwith the face ofthe partition, or project therefrom to any suitable distance; the heatpassing'throngh the flues is, by my invention,

utilized for heating the apartment or car by;

its being diffused'zthrough the metal chimney,- a large amountof'heating-surface being thus exposed in the apartment. The main trunkmay be carried up at the intersection of. two I partitions,and thus fourfire-places can b} com- ,bined in the base B, so that one fire-ha ket evmay be provided =to each ofthe four partments, the base B being arrangedaiiglewise at the corner of each room.
